It is also at least half-year old, so AMD is very late to the party with their Istambuls.
look at the pic you posted it has 3 banks of 45nm cores now go look at the AMD design
istanbul is a true 6 core design while the intel version is a bunch of dual cores grouped together that talk accross the FSB. the size and number of cores possible in the system dont really matter to what i said so i do not know why you brought it up... and the 8 series istanbul chips will allow the same thing from AMD.
